Short Answer 
The answer indicates that Option D is correct and explains that “The Importance of Being Earnest” by Oscar Wilde critiques societal views on marriage, showcasing it as trivialized through comedic dialogue. The analysis highlights how characters’ flippant attitudes towards proposals reflect a deeper commentary on the institution of marriage in Victorian society.
Step 1: Understand the Context of the Play
“The Importance of Being Earnest” is a comedic play by Oscar Wilde that debuted on February 14, 1895. Set in the Victorian era, it explores critical themes such as marriage and societal norms. The characters engage in witty dialogues that reflect on the seriousness, or often the lack thereof, associated with marriage in that time.
Step 2: Analyze the Characters and Their Views
The dialogue presented features Gwendolen, who humorously points out that her brother proposes to all her friends merely to practice his proposal. This highlights a satirical take on how marriage was viewed in society. The characters discuss the institution of marriage, often suggesting it holds significant importance, yet they treat it in a flippant manner.
Step 3: Recognize the Underlying Message
The essence of the dialogue reveals a critique of a society that trivializes proposals and marriage. By illustrating that proposing has become a routine practice devoid of depth, Wilde emphasizes that marriage, which should hold profound significance, is instead approached with a casual attitude. This commentary encourages the audience to reflect on the true nature of marriage and its implications in society.
